Question

我有一个带有字体真棒图标的按钮组，并且其中一个下拉菜单如下图所示。我想切换按钮状态。但是在mouseout上，.active类会被自动删除。这似乎与focus中所有.btn类的bootstrap.js事件捕获有关。 $().button("toggle")也会发生这种情况。

我该如何解决？

.btn-group-toggle在下拉菜单中不起作用。

$('#tools button').on('click', function () {
if (this.id == 'select') {
  // FIXME: The active class gets removed immediatly somehow
  $('#pencil').removeClass('active');
  $('#select').addClass('active');
} else {
  $('#pencil').addClass('active');
  $('#select').removeClass('active');
}
});

您可以尝试使用Event.stopPropagation()：

$('#tools button').on('click', function (e) {
  if (this.id == 'select') {
    $('#pencil').removeClass('active');
    $('#select').addClass('active');
    e.stopPropagation();
  } else {
    $('#pencil').addClass('active');
    $('#select').removeClass('active');
  }
});
